Out of curiosity, why is that?
Edit: I Google’d:
“ Electric vehicles boast instant torque, meaning they accelerate the second you put the pedal to the metal. However, the high instant torque of electric vehicles can also increase wear and tear. In addition to good grip, the rubber compound used for EV tyres also needs low rolling resistance.”
And
“ Teslas are heavier than most other cars because of their battery packs, which can add hundreds of pounds to the vehicle's overall weight. This extra weight puts additional strain on the tires and leads to increased friction between the tires and the road surface, which causes them to wear out faster.”
- justsomehnguy 3y ago"Compared to a similar ICE vehicle" It maybe a false memory effect but I vague remember this notion about trolleybuses.
- xbmcuser 3y agoWhile watching this video I was thinking will this solve the tyre particulates problem https://youtu.be/vSNtifE0Z2Q https://youtu.be/vSNtifE0Z2Q
- Vecr 3y agoNo way, the grip on a normal road with those tires would be terrible. They would also be destroyed very quickly. They are designed for off-road low-speed applications. Low rolling resistance rubber tires are much more efficient energy wise as well. Rubber tires are very advanced anyway, many use chlorobutyl blends and steel and/or Kevlar reinforments.
- viraptor 3y agoThat seems like a temporary issue. Right now we've still got lots of expensive/high class EVs where ludicrous mode is a thing people are excited about, but once there's real competition on the low end... "doesn't waste tyres" sounds like both a good selling point and simple to implement.
- dzhiurgis 3y agoI think we are already there. The best selling Tesla right now is also a slowest Tesla ever made - Model Y SR at pretty limpy 0-60 of 7s (which is perfectly fine and fun to drive). p.s. Seeing how many people already killed themselves with Plaid - I think gov should require advanced driving licence for super quick and super fast cars.
- rgmerk 3y agoAdvanced driving courses have a decidedly mixed record on improving safety, unfortunately. I believe the evidence suggests that they improve confidence more than they improve skill. As for the Plaid, from what I’ve read the yoke and the high-speed handling are frankly dangerous. If somebody gave me one, I’d sell it and buy something where the drivetrain, the handling, and the aerodynamics are better matched.
- saurik 3y agoI am under the (maybe wrong?) impression that the former issue is helped a lot by telling the car to accelerate in Chill mode instead of Standard, which causes it to purposefully carefully ramp a derivative or two of acceleration.
- hedora 3y agoIt helps less than you’d think. Part of the issue is that the tires are ultra low rolling resistance, and part is that the car weighs an extra ~500 lbs.
- saurik 3y agoThe car weighing a lot is the second issue, though, not the first. Is the ultra-low rolling resistance a third issue, or related to one of the other two?
- xattt 3y ago> Electric vehicles boast instant torque, meaning they accelerate the second you put the pedal to the metal. However, the high instant torque of electric vehicles can also increase wear and tear. It seems like this factor could be easily solved with torque output adjustments, but it won’t be unless it’s regulated. The unwashed masses now expect every BEV to be performant without knowing the maintenance costs of actual ICE performance cars. Manufacturers feed into this, as dealers love to have repeat customers for an otherwise low-maintenance car.
- lazide 3y agoHuh? BEV maintenance costs are way lower than ICE, even if brakes and tires need replacing a little earlier than the ICE equivalent.
- seanmcdirmid 3y agoIt’s just too hard to resist pulling out of an intersection with lots of acceleration. I’ve more than a few times heard my wheels squeal going from stop to 25 in a couple seconds.
